Dynamic LoD for QoS management in the next generation VRML

A high speed computer network will provide us with new broadband multimedia applications. This paper discusses new functions for the next generation VRML (Virtual Reality Modeling Language) over high speed computer networks. The LoD (Level of Detail) of 3D objects is the most important function for rendering scenes dynamically while managing the QoS (Quality of Service). New requirements for the next generation VRML are discussed. We present Differential VRML (DVRML) in order to update scene graphs dynamically, and describe principles of the LoD function based on the DVRML.

Concept and Design of SDN-Enhanced MPI Framework

In general, modern high-performance computing systems are built as cluster systems. We have been investigating the feasibility of optimizing MPI communications by integrating the dynamic network control realized by SDN. In this paper, we present a concept of a generic SDN enhanced MPI framework, an application-aware network control mechanism specifically for MPI applications.
